The fluid was pretty dark. It has been doing this for about 2 months actually...hasnt got much worse. I know all that hard shifting cant be good for her though.

It is possible to get the car running better with automatic transmission fluid changes if the fluid is dark or even brown/black. However, if it gets to the point that the fluid is brown or black the transmission is likely already burnt up and you're just saving a bit of time before complete failure. If you catch it in time before it gets really dark and is burning up a fluid change will help to dissipate heat and might possibly prolong the life of your transmission to the point of being useful again.
ATF fluid for us automatic owners is the Spice Melange. The spice extends life. The spice expands consciousness. It's the most precious substance in the universe to the 626 automatic. Oh and you might want to read this and this.

I do not know what was causing the problem but I would assume it was some kind of faulty sensor. I did end up selling the car for a loss. This car is such a piece of junk I can't believe it even has such a fantastic website devoted to it. Why anyone cares anything at all about this junk is beyond me, but I am grateful he resource is/was here.
I will again ask that this thread is moved to the technical section where hopefully someone experiencing the problem can find some helpful information. Good day to all of you fine people, but I would never ever EVER even think about buying another one of these cars.

Changing the trans fluid is a good start but adding an external trans cooler to your system is best. But if your transmission is already 'dying' (due to not dealing with the problem sooner) then a new or rebuilt or converting to manual trans or selling is in your future.
Any and all 'older' cars need regular maintenance in order to last. Not dealing with problems right away can be 'costly' and inconvenient later on. Certainly, the 626 with the CD4E auto transmission isn't great but with some 'loving care', it can be a fun and reliable car to drive.....my 98 auto trans has 163,000 miles....rebuilt @ 93,000 then added external cooler.....runs great! Knock On Wood!

Checked transmission fluid; it's OK and no burned smell.
How to proceed to determine what's wrong from here?

but my 2002 4cyl with the ATX has 208k miles on the <ORIGINAL> motor and transmission. Yes it's the FSDE motor and CD4E transmission. It had an external transmission oil cooler installed along with the cooler built into the radiator. When it's cold out the 1-2 shift is hard. Everything else is butter smooth. When it warms up it smoothed out. Also if I accelerate hard it shifts smooth from 1st to 2nd.
It's also a known fact that the shift points in this transmission (and other Mazda's) is set harshly. The 2005 Mazda3 I drive every now and again also has a hard shift from 1st to 2nd.
So you can't take it out on the car. The previous owner most likely abused the piss out of the car and didn't give 2 shakes to the condition when he sold it.

My 1997 626 is throwing codes P0743, P0750, P0755 and P1788. The OD light blinks from the time the engine is started. Any Ideas ????

P0743 - Torque Converter Clutch Circuit Electrical
P0750 - Shift Solenoid A Malfunction
P0755 - Shift Solenoid B Malfunction
P1788 - 3-2T/CCS Circuit Shorted
you have some serious transmission error codes there. Take it to a
professional transmission shop for service. It's possible your
transmission will fail to shift at any time including while coasting on
the highway and not even in the middle of a shift.
